Industrial hot air blowers perform an essential function in many industries, with applications ranging from drying and De-moisturizing to defrosting, thawing, warming, heat shrinking, flaring, etc. They are an essential piece of equipment in food processing and packaging, metallurgy, chemical, construction, printing, textiles, leather, opencast mining, electronic assembly industries, etc. Because they are such an essential piece of equipment, many different types are available.
The nomenclature used for hot air blowers varies according to the industry. It is also called a hot air gun, heat blower, or heat air blower. Hot air blowers are generally used as a hand tool that blasts a concentrated amount of hot air onto the specific target area so that it can melt, dry, heat, loosen, remove, and even shape plastic. Industries frequently use heavy-duty hot air blowers, which, when attached to an industrial-grade electric hot air blower gun, become essential equipment.
Broadly speaking, industrial hot air blowers can be divided into the following categories based on their use and fuel source:
The specifications of industrial hot air blowers vary depending on the type and model. The following table shows some standard specifications with descriptions.
Sizes
Industrial hot air blowers come in different sizes. Big ones are suitable for large-scale production, while small and portable ones are ideal for smaller space constraints.
Power rating
The power rating of an industrial hot air blower is usually between 1 and 5 kW. It determines the heating capacity and output of the equipment. A high power rating means that the air blower will heat up and blow out hot air faster.
Temperature control
An industrial hot air blower generally has a temperature control setting that allows the users to adjust the temperature as per their needs. It can range from 250 to 700 degrees Celsius or even higher in some models.
Airflow volume
The airflow volume determines the amount of air the blower will circulate. It is measured in cubic meters per hour (m3/h) or liters per minute (L/min). The average airflow volume ranges from 0.5m3/h to 10m3/h.
Noise level
The noise level of industrial air blowers is measured in decibels (dB). Some blowers can be as loud as 90 to 95 dB. Using noise-cancelling earphones or earmuffs with industrial air blowers is recommended for hearing safety.
Power source
An industrial air blower can be powered by electricity, natural gas, or propane. Some models even use renewable energy sources such as solar energy or diesel fuel.
Proper maintenance increases the lifespan of the industrial hot air blower and prevents sudden breakdown. It is important to clean the equipment regularly. Wipe the exterior of the blower with a damp cloth to remove any dust and dirt. Use compressed air to clean the radiator fins and heat sink. This prevents the build-up of any debris that may block the area. If the air blower has a filter, it should be cleaned and checked periodically. Users should replace the filter if it shows signs of damage or excessive dirt.
Keep the surrounding area of the hot air blower clutter-free and well-ventilated. Businesses should schedule regular inspections to identify any potential issues with the equipment. The electrical connections, fasteners, heater elements, and blow fan should be checked and tightened if necessary. If there are any signs of wear and tear, repair or replace the parts as required. To avoid overheating, do not exceed the recommended temperature settings. Refer to the manufacturer's manual to understand the precise temperature range blowers can function in.
Lastly, proper storage is essential. For long-term storage, the hot air blower should be kept in a dry place, away from direct sunlight and extreme environmental conditions, such as high heat or cold. Using the industrial air blower at the stable voltage recommended by the manufacturer is crucial. A fluctuating voltage can damage the internal electrical components of the equipment.
Industrial hot air blowers are versatile tools used in different industries for various applications. Below are some of the common uses of an industrial hot air blower:
Drying
An industrial hot air blower is commonly used for drying different products and surfaces. The high-temperature airflow effectively removes moisture from materials such as wood, paper, textiles, food, chemicals, and construction materials. It speeds up the drying process, improving productivity.
Heating and Shrinking
The presence of adjustable temperature settings on industrial hot air blowers makes it possible to apply heat gently to different materials. Heat application can increase material flexibility, enhancing process operations such as bending, sealing, assembling, and tightening. An air blower is widely used in the electrical industry for heat shrink tubing. With the help of hot air, heat shrink tubing can easily shrink and create a protective and insulated fitting around wires and connectors.
Removing Paint, Coatings, and Adhesives
An industrial hot air blower can remove paints, coatings, and adhesives. An air blower heats up the paint or coating when directed on a surface, causing it to blister and lose adhesion. This makes it easy to scrape or peel off the heated material. The process is more efficient than using chemical strippers and provides better control.
Welding and Soldering
An industrial hot air blower is used for plastic welding. The tool joins plastic components by melting the edges with hot air. The resulting strong bond reduces the need for additional fasteners. An air blower is also used for soldering electronic components, such as joining wires and connectors, and enabling quick and precise soldering.
Thawing and De-icing
In winter and cold climates, an industrial hot air blowers helps to melt ice and frost buildup on various surfaces. This includes railways, pavements, roof gutters, water pipes, and frozen locks. By applying hot air to the ice, temperature differentials cause it to melt quickly, preventing potential damages and safety hazards.
For business buyers, it is essential to consider the following factors of industrial hot air blowers before purchasing.
Airflow:
Flow rate, typically measured in cubic feet per minute (CFM), describes the volume of air a hot air blower engine delivers. Higher CFM generally results in greater drying speed and coverage. However, selecting a model that fits the specific application is essential since excessively high CFM may create noise and power consumption unnecessarily. A balanced approach between a machine's CFM, utilization, and efficiency should be maintained.
Temperature Regulation:
Industrial hot air blowers are available in different operating temperature ranges. Certain applications may require more heat, while others can use a more moderate level. It is crucial to select a blower that provides temperatures high enough for the specific job without the risk of damaging sensitive components or materials.
Fuel and Power Source:
Hot air blowers use various energy sources, including electricity, propane, kerosene, natural gas, or diesel. Each fuel has its advantages, such as portability, efficiency, and environmental impact.
Noise Level:
Consider the noise level generated by the hot air blowers and whether it complies with local regulations and requirements. If the business requires operating in a noise-sensitive environment, opt for a more silent model. Alternatively, if the hot air blower produces high noise, ensure adequate hearing protection for workers.
Cost
Business buyers need to consider the initial purchase, installation, operating, and maintenance costs. While a more affordable upfront price may look attractive, it is essential to evaluate long-term expenses and the potential need for early replacement.
Q1: What is the difference between a hot air blower and a heat gun?
A1: A hot air blower is more suitable for elaborate applications that require the airflow to be high while maintaining low energy consumption. Blowers generally have a more powerful motor and impeller system than heat guns. On the other hand, heat guns are handheld devices that provide high-temperature output, and they are more compact and portable.
Q2: Does the temperature of the industrial hot air blower affect the price?
A2: Yes. Generally, higher-temperature hot air blowers tend to be more expensive because of the additional costs associated with the production and also the benefits they can provide.
Q3: Does the amount of airflow affect the price of an industrial hot air blower?
A3: Yes. An industrial blower machine that provides higher airflow is usually more extensive. The installation of the machine will also be more complex. Higher airflow hot air blowers are used in more demanding industrial applications. Therefore, the price is higher.
